1. An electrochemical arrangement
with a first and a second metallic separator plate which each define a plate plane and which are stacked in a stack direction perpendicularly to the plate planes;
with an electrochemical cell which is arranged between the separator plates;
wherein the separator plates each comprise at least one sealing element which is embossed into the separator plate and which rises above the respective plate plane;
wherein the sealing elements of the separator plates are supported against one another for sealing at least the electrochemical cell which is arranged between the separator plates;
wherein the sealing elements of the separator plates are elastically deformable in the stack direction, so that a distance z of the plate planes of the separator plates to one another is reversibly reducible at least to a distance z2 by way of an elastic compression of at least one of the sealing elements of the separator plates; and
with at least one support element which is arranged between the separator plates and which is distanced to the sealing elements of the separator plates in a direction parallel to the plate planes of the separator plates;
wherein the sealing elements of the separator plates and the at least one support element for protection of the sealing elements of the separator plates from an irreversible plastic deformation are configured such that when the distance z of the plate planes of the separator plates to one another is reduced to a distance z of z≤z2 as a result of a pressing force which acts upon the separator plates in the stack direction, a force FS which is required for compressing or for the further compressing of only the at least one support element by a displacement Δz′ in the stack direction is larger than a force FD which is required for the further compressing of only the at least one sealing element of the separator plates by the displacement Δz′ in the stack direction.
